Im getting this annoying beeping noise with 2-5 minute intervals while driving. My check engine light is not on. It almost like when you need a oil change. If this is what it is, can someone tell me how to reset it. Thanks!!!!

 

perhaps your tire pressure sensor? That is the only thing that I know of on the SC430 which will give you the constant beeping noise. Is your TPS warning light on (left side of your speedometer)?

 

I noticed my low pressure warning light on, then later that day it started flashing and beeping as you described. I had a flat. Got it patched and the light went off. I never heard the beeping before that.

 

Do you have tire sensors in your 20"?
If not, you need to unplug the module under radio.

 

Mine beeps like crazy when drifting!
